State Oversize & Overweight Permitting & Escort Protocol Guide
The multi-state heavy haul compliance authority: master state DOT travel curfews, pilot car escort ratios (lead, chase, and civilian height pole), holiday travel bans, and Bridge Formula B axle compliance.
Metro Curfew Clocks
Major metropolitan corridors (Chicago, Atlanta, Dallas-Fort Worth, Houston, Los Angeles) prohibit oversize transit during morning (6:00 AM – 9:00 AM) and evening (4:00 PM – 7:00 PM) rush hours. Running an unpermitted curfew risks immediate impound and thousands in fines.
Pilot Car Escort Ratios
Every jurisdiction maintains differing trigger points for front vs. rear escorts. Loads over 14'6" height mandate a lead car with a calibrated fiberglass height pole set 6 inches above load height to verify bridge clearances.
Bridge Formula B & Axle Spacing
Overweight permits don't just assess Gross Combination Weight (GCW)—they calculate pounds per inch of tire width and bridge stress based on distance between the outer steer and booster axle groups.

The 4 Pillars of Heavy Haul & Oversize Fleet Dispatch
1. Electronic Permit Sync & Route Locking
Carriers cannot deviate from granted state DOT route paths. Exspeedite links granted electronic permits to the driver's in-cab tablet, alerting dispatch immediately if GPS telemetry wanders off designated permitted roads.
2. Pilot Car Telematics & Insurance Verification
Ensure civilian escort vehicles maintain active $1M commercial auto and professional escort liability insurance. Exspeedite tracks third-party escort credentials alongside driver assignments.
3. Bridge Load Rating & Superload Analysis
Loads exceeding 150,000 lbs require state structural engineering bridge reviews. Exspeedite logs axle group spacings down to the inch, ensuring rapid submittal and approval.
